Then said Jesus again unto them,
I go my way, and you shall seek me, and shall die in your sins: where I go, you cannot come.
All Commentaries on John 8:21 Go To John 8
John Chrysostom
AD 407
As if to say, No wonder that you think as you do, seeing you are carnal, and understand nothing spiritually. I am from above.

For if He came in order to take away sin, and a man cannot put that off, except by washing, and cannot be baptized except he believe; it follows, that he who believers not must pass out of this life, with the old man, i.e. sin, within him: not only because he believes not, but because he departs hence, with his former sins upon him.
